LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 623,848, dated. April 25, 1899.

Application filed July 19, 1898- Serial No. 686,331. LNo mocleh! To (tZZ whmn it ntcty concern.-

Be it known that I, ALBERT EDWARD STIRCKLER, engineer, a citizen of the United States, and a resident of 26 Billing road, Northampton, in the county of Northampton, England, have invented certain new and useful Improvements in Machines for Lasting Boots and Shoes, which invention is fnllyset forth in the following specification.

This'invention relates to improvements in certain parts of the lasting-machine for which I have applied for United States Letters Patent on the 24th day of December, 1897, Serial No. 663,364. In the machine described in the specification accompanying the said application thelast,with the upper to be lasted thereon, is clamped between toe and heel clamps or heads carrying wiper-plates which wipe the toe and heel ends of the upper over onto the last. The toe clamp or head carries a gripping-jaw, between which and the wiper-plates the upper is held. A rising motion is given to the said clamp, while the last is prevented from rising by a rod carried by the clamp being held in contact with the last, and by the pressure exerted on the said rod the clamp and the gripping-jaw, with the upper held between them, rise and stretch the upper, which is then wiped over the toe of the lastbythe for ward movement of the wiper-plates. Side drafting nipper wipers are also provided which stretch the upper over the sides of the last, and it is to these parts of the machine that my present invention has special reference; but it also has reference to other parts of the machine, which will be hereinafter described with reference to the accompanying drawings. v

extreme toe end of the last and for assisting in holding the said toe end of the upperin its stretched position. Fig. 5 is a similar view of the pad for pressing against the heel of the last.

heel-pad for holding the heel portion of the upper in position on the last. Fig. 7 is aside elevation of one of the outside blocks of a set of three blocks, which carry the draftingnipper wipers for stretching the upper over the side of the last; Fig. 8, an end view of the said block, and Fig. 9 is a plan of the same. Fig. 8 is a sectional elevation of part of the center block. Fig. 10 is a side elevation of the mechanism for operating the side draftingnipper wipers and for restricting the movement of the blocks carryingthe said draftingnipper wipers. Fig. 11 is an end elevation of one of the slides carrying the blocks on which the side drafting-nipper wipers are mounted, and also the mechanism for restricting the movement of the said slide; and Fig. 12 shows in elevation a device for permitting the side drafting-nipper wipers being disengaged from and engaged with the upper while the toe and heel supports are in their operating position.

Referring to Figs. 1 and 2, A represents the rising portion of the toe clamp or head hinged at 1 to a block 2, carried on the upper ends of rods or studs 1 surrounded by springs 3, which bear at their lower ends on nuts 3 screwed onto the lower ends of the said rods or studs and at their upper ends against the under side of the longitudinally-sliding plate 5, carrying the portion A of the said toe-head,the said springs permitting of the clamp yielding to the desired extent for the lasting operation, the toe-rest determining the height to which the clamp is permitted to rise and also admits of the head rocking in a lateral direction on the stud 4 4 are guides provided on the plate 5, between which guides the block 2 is fitted to slide up and down. So far this mechanisin is the same as that described in the application hereinbefore referred to. According to my present invention I provide on the plate 5, so as to slide thereon, a frame 13, hav- 'ner, the said clamp can be maintained in its elevated positions by moving the lever O in the direction to bring the wedges B beneath rollers 0, carried on the spindle or hinge-pin 1, which connects the block 2 to the portion Fig. 6 is a plan of the heel clamp or 4 head provided with a divided heel-ring and A, which hinge-pin is mounted in bearings 2 on the under side of the said portion A of the clamp, the wedges thus inserted admitting of the last with the upperlasted thereon being released and removed while the clamp remains elevated, and thus prevent any liability to abrade the upper when removing the last from the machine.

In the modification illustrated by Figs. 3 and @l: the wedges B are made pointed, so as to be capable of entering beneath the roller 0 on the extreme forward end of the portion A of the clamp, beneath which rollers the said wedges may be forced by the lever C when the portion A of the clamp is in its normal lower position, and so raise or assist in raising the said clamp. These wedges are employed in the manner described when strong material is being stretched on the last, but are capable of being moved out of action, the said wedges having slots i therein, through which pass studs from the frame B, on which studs the wedges can be slid and be affixed in position by nuts 1?, screwed onto said studs. \Vhen the upper consists of a lighter material, the wedges 13 are fixed in their backward position and other wedges 13 carried by the frame 1 brought forward to act on rollers .43, carried by the block 2, to which the clamp A is pivoted. The wedges B or B may be employed alone for raising the toe clamp or head and the elevating device carried on the top plate of the clamp be dispensed with, in which case anysuitable gripping device with an adjustable downhold may be provided to grip the upper between the said gripping device and the wiper-plates carried in the said clamp or head. The toe clamp or head is provided with an adjustable pad (I, Fig. 5, which is provided with a conical projection (1', fitting a corresponding recess in the holder (Z screwed onto a screwthreaded rod and pressed forward by a spring, so as to cause the pad (Z to press upon the upper at the toe end of the last and smooth the said upper at this part and retain it in its stretched position. The said pad is free to turn or rock in the holder (Z to accommodate itself to the shape of the toe of the last whether it be a left or a right, and it can be readily removed from the holder and a pad of different shape be fitted in its place.

Theheel clamp or head A as shown in Fig. (3, is provided with a pad 6, (shown separately in Fig. 5,) similarin construction to the toepad (Z and removable from the holder to admit of pads of different sizes and shapes to suit the size and shape of the lasts being readily fitted to the said holder. This heelpad projects from the clamp beneath the wiperplates carried on the said clamp to bear against the upper atthe heel end of the last, which pad can be caused to project more or less from the said head by an adj listing-screw 6. Instead of the ordinary band hitherto employed for grasping the upper round the heel of the last I provide plates c to bear on the upper at the opposite sides of heel portion of the last, the said plates being pressed against the said upper with a yielding pressure by springs a interposed between the plates 6 and shoulders in passages in the head through which the stems 6 pass, which plates, in conjunction with the pad a, serve to hold the last in proper position for the correct wiping over of the heel portion of the upper by the wiper-plates carried in the said heel clamp or head. The plates 0 can be adjusted in position to suit lasts of different sizes and shapes by means of nuts c, screwed onto the stems a, carrying the plates The drafting-nipper wipers for stretching the upper at the sides of the last in machines of this kind hitherto in use are pivoted to sliding bars, so that they can be turned in a horizontal plane on the said slidingbars, and the said bars are caused to slide in a direction at right angles to the center line of the last. Consequently the upper, which is engaged in the nippers, is pulled in the said right-angular direction.

According to my present invention, as shown in Figs. 7, S, and 9, each drafting-nipper F is mounted on a stud f, projecting from the forward end of the sliding bar 1'', so as to be capable of rocking on the said stud, but it has no movement in a horizontal direction on the said sliding barf. The block F, in which the barf slides, is hinged at f tolngs formed on a screwed stem f situated in a vertical hole in a block F beneath the block F and screwing into a nut f, adapted to turn in a notch or opening f in the said block F so that by rotating the nutf the block F can be raised more or less from the block F to permit of the drafting-nipper easily passing over the side of the last. The screwed stem f can turn freely in the vertical hole in the block F so that the block F can turn in a horizontal plane, which horizontal movement can be restricted by a pinf in the block F coming into contact with the ends of a notch f in the under side of the block F. The block F can also turn in a vertical plane on the hinge f the said Vertical movement being restricted by pinsf in the block F traversing notches f in the lugs to which it is hinged, or vice versa. The blocks F carrying the outside drafting-nipper of each set of drafting-nippers on opposite sides of the last, can be separately adjusted in position in base-plates F nearer to or farther from the center block to suit lasts of differentlengths, by means of screws f, as shown in Fig. 8-, working in corresponding screw threads in the two outside blocks F of the set of drafting-nippers to adjust the two outside blocks F The base-plates F in which the blocks F slide, can be adjusted and fixedin position on the frame of the machine, nearer to or farther from the longitudinal center line of the last, as required, to suit rights or lefts, for which purpose slots f are provided in the base-plates, through which slots screwed studs f on the frame of the machine pass and on which studs nuts f are screwed to fix the said base-plates in their adjusted positions.

By arranging the blocks F to turn in a horizontal plane in combination with the adjustability of the blocks F nearer to or farther from each other the slides f, carrying the drafting-nippers, can be arranged to pull the upper engaged by the said nippers in any desired angular direction with reference to the center line of the last, and the nippers can be engaged wit-h the upper at any point desired, so that the drafting of the upper can be efficiently effected in any desired direction. For instance, the blocks carrying the center nipper and the outside nipper nearest the toe end of the last can be turned to such an angle that the nipper can be engaged at the most advantageous points to stretch the upper toward the toe of the last, while the block F carrying the nipper on the other side of the center nipper, can be arranged to stretch the upper in the direction toward the heel of the last and so prevent any fullness of leather in the waist of the last. The slides carrying the drafting-nippers are operated by rods and levers 63, 63 63 and 64, actuated bya cam or wedge 70 and sliding rods 67, the fulcra of said levers being carried in brackets g on the base-plates F in which the blocks F 'on opposite sides of the last slide, as shown in Figs. and 11. Each base-plate'is provided on the under side with a recess 9 extending to a distance of, say, about two-thirds across the said base, and on a projection g on the frame of the machine on which the base can slide there is a corresponding recess g. In these recesses is placed ahelical spring 9*, which bears at one end against the end of the recess in one of these recesses and at the opposite end against the end of the other recess, so that when the base-plate F is moved outward from the center line of the last the said spring will be compressed between the ends of the two recesses and will return the baseplate to its normal position when the pressure forcing it outward is removed. WVhen the forward movement of the nippers is retarded by tightening the upper over the last, the base-plates F tend to slide outward on the projections g against the power of the springs, which are thereby compressed between the opposing ends of the recesses g 9 unless the outward movement of the base F is prevented. The outward movement of the base-plate on either side or on both sides of the last can be prevented by locking-bolts g coupled together by a two-armed lever 9 centered to a pivot g adjustable in the frame of the machine. The bolts g are arranged to slide on studs 9 in avertical direction on the frame of the machine, the said studs 9 passing through slots g in the bolts. By moving one of these bolts up or down the lever 9 will rock on the pivot g, and the other bolt will be moved in the opposite direction,

so that when the outward movement of the base-plate on one side of the last is retarded by one of the bolts the base-plate 011 the other side of the last will be free to move outward against the pressure of the spring 9*. The bolts g may, however, be moved into an intermediate position,so that the base-plates F on both sides of the last can be free to move outward, or by raising the adjustable pivot g both baseplates F can be prevented from moving. The base-plate on that side of the last which is most hollow at the waist should be the one prevented from moving outward so that when the drafting-nipper on the straighter side of the last com es to rest the base-plate will move outward and compress the corresponding spring 9*, while the base-plate on the opposite side of the last being prevented from moving outward the drafting-nipper on that side of the last will be caused to move farther inward toward the center line of the sole of the last and stretch the upper more closely to the last at the waist.

The shaft 7l,which carries the cam or wedge 7 0, when rotated imparts to the side draftingnippers their movement toward the longitudinal center line of the last. A detent 73 engages the teeth of a ratchet-wheel 7 2* to prevent the shaft from moving back, and it is necessary to disengage this detent from the ratchet-wheel to permit of the last being removed from the machine. In machines of this kind hitherto in use the detent is retained in gear with the ratchet-wheel by a projection from the lever 88, by which the heel-support is operated, and it is necessary to move the said lever 88in the direction to lower the heel of the last, and thus place the parts of the machine out of position to release the said detent. According to my invention the said detent can be disengaged from and held out of engagement with the ratchet-wheel 7 2* without shit'ting the lever 88. A convenient arrangement for this purpose is to connect to the tail end 75 of the detent 73 a wire or rod h, provided with a loop h to engage with a hook h2 on the lever 64 or any other suitable part of the machine to hold the detent out of engagement with and permit of the last being released and removed from the machine and another last of the same size placed in the machine without lowering the heel and toe supports or disarranging other parts of the machine.
